l SPRAYING AND WASHING DEVICE.

Application ma Auguit 5,1923. `serial No. 65am.

To all whom t may concern;

Be it known that l, FRANCIS W. KELLE- BLER, a citizen of the UnitedStates, and a resident of Cambridge, in the count of Middlesex andCommonwealth of ssachusetts, have invented certain new and use- JIIulmprovements in Spraying and Washing Devices, of which the following is afull,

clear, and exact specilication. D

rlhis, invention has for'ts object the construction of simplified andetlicient means whereby to eject a. liquid solution of insectdestroyingpoison, or for jetting either water alone, or water and a cleansingmixture i A upon automobiles andthe like.

In carrying my invention into effect l prefer 'to adapt the device forattachment to a hose or faucet and to employ the stream of water forproducing a vvacuum which acts to .take up kerosene, a saponiiedsolutionhor other liquid, and to discharge the same with the jet orspray of water upon the automobile or other painted surface to becleansed; or, if the liquid contains an 1nsect-destroying mixture, uponthetrees or plantsto bepreserved.

Im the drawings forming part of this specification, Fig. 1 is an outsideview of the suction and mixing 'chamber of the device. Fig. 2 is acentral longitudinal section of the same. Fig. 3 is a cross section onthe line 3 3 in Fig. 1. Fig. 4 is a view on a smaller scale showing thedevice connected with a brush. In the form of the device shown in 1 to4, a tubular body 1 is designed to screwed upon the end of a hose 2, ora faucet or other source of water under pressure, and a nozzle 3 isscrewed into its opposite end. 40 This nozzle has preferably a taperinghole 4 through it and an inwardly extending projection 5, the smallestdiameter being in its outer end. v

Between the nozzle 3 and the internally threaded section 6 is a chamber7 having longitudinally positioned therein a plug 9 preferablyverticallyv fitted within the -walls of the chamber 7 but leaving spaces10 between its vertical sides and the chamber walls for the passage ofwater. F-rom the end of the plug 9 adjacent the projection 5 reaches aslender tube 11, the inner diameter of which is approximately equal tothat of the outer end of the hole 4.

The relative position of the ltube 11 and extension 5'is lveryimportant, as will be explained later, since not only must they be inapproximate alinement, but the space between their ends mustfnot be toolarge or too small. To enable this space to be regulated, ll prefer toVplace a washer 12 between the shoulder 13 of the nozzle 3 and the endof the body 1, whereby a varying of the thickness of such washersenables me to obtain the exact space required.

Vertically through the body 1 and also the plug 9 extends a `slendervalve 14 slightly tapered in order to ensure a water tight iit both inthe walls of the chamber 7 and in the plug 9. A radially disposed hole15 in the valve in alinement with the bore of the tube 11, and an axialhole 16 drilled from the lower end of the valve into communication withthe hole 15, enable any `fiuid to pass from the lower end of the valveinto the tube 11. By partially turning theA tube 20.

In the use of this device for cleaning an automobile or f.:y partethereof which are more or less oil the tube 20 has its lower endintroduced into quantity of kerosene, and then the water is turned on.As the water is urged past the ends of the tube 11 and ,extension4 5 andout throughl the hole 4,. a powerful suction is created through the tube11, holes 15, 16 and the hose 20 suiiicient.

to bring up and mix with the water ejected from the nozzle 3 enoughkerosene to cut any oily accumulations upon the running gear or votherparts of the automobile; which accumulations, after being cut by thekerosene, are washed away by the jet of water, either by the wateraccompanying the kerosene, or by water alone after the valve has beenturned to shut oi the further admission of the oil. f

nFor such parts of the automobile as are not oily, but are coated withdust and mud,

the tube 20` is removed from the` lierosene l and dipped into a solutionof soap and water, and the cleansing continued 1n the same manner, thevalve being closed when the soap water is tov be washed oil'.

For t e spraying of tr'ees, shrubs andI plants, the tube 20 is'introduced Iinto a liquid germicide mixture, and the work continued inmuch the same manner as above described.

WhilegI have described the device as especially applicable to automobilewashing, it is also well adapted for washing the outside of windows2either on the first or second floors. .For thls purpose, the saponifiedwater is first used, and then the water alone to remove all traces ofthe soap.

The brush 22 can be attached directly to the device, screwing it uponthe threaded end 21 so that the solutions will pass through its back andbe received in its bristles, or it can be attached to a hose -connectedwith the end 21.

As shown in Fig. 2, the valve 14 maybe entirely tubular, so that itshole 16 reaches from end to end thereof. Thus constructed, there can beno suction up through the tube 20, since the atmosphere has free accessto the tube 11, but by the mere placing of the operators thumb upon theopen upper end the suction instantly begins to act.- ,This is veryconvenient in washing a car, since it requires only a quick movement ofthe thumb to discontinue the s raying of the soap or kerosene and throwt e water alone; and then at another part of the car to begin with thecleansing compound again.

What I claim is:

1. A spraying and washing device comprising a chambered bold a nozzle atone end, an opening at the ot er end for receivvin water under pressure,a plug removably held in the chamber and provlded with a tubular portionterminating near the inner end of said nozzle, a slender valvepenetrating said plu transversely' from the exterior of said bo y, andmeans for admitting a`li uidto said valve, the latter havingv an.

axia hole and a radial hole adapted'to be chamber but narrower than thelatter to l.

permit the passage of the liquid between it and the chamber-wall, laslender tube prof jecting from said plug nearly to the inner end of saidnozzle, a tubular valve member extending transversely through said bodyand plug parallel with the wider sides of said plug and having a radialhole adapted* to be put into communication with said tube, and a sleeveadapted tol be fastened upon the lower projecting end of said valve,'the upper end of the latter having means for turning it. v

3.' A spraying and washing device com;

prising a body having an opening for receiving a liquid under pressure,a nozzle, a

valve, and means attac ed to the lower end4 of said valve for admittinga uid thereto, whereby the said valve being open to the Atubular valve,means for creating a vacuum atmosphere at its up er end, there can be ino action upon the fluid until after the same i1 cloed, as by thepressure of the operators t um In testimony-that I claim the'foregoinginvention, Ihave hereunto set my hand this 4th day of Au st,1923.
